Acute prognosis of critically ill patients with secondary peritonitis: the impact of the number of surgical revisions, and of the duration of surgical therapy

Abstract Background Duration of surgical therapy and the number of surgical revisions performed to control the focus may be important prognostic variables. Association of such time-dependent therapies with survival, however, has not yet been studied. Methods We analyzed survival times of adult patie...

description Abstract Background Duration of surgical therapy and the number of surgical revisions performed to control the focus may be important prognostic variables. Association of such time-dependent therapies with survival, however, has not yet been studied. Methods We analyzed survival times of adult patients (n = 283) who were suffering from secondary peritonitis and associated organ failure. Cox-type additive hazard regression models were used to analyze associations of surgical variables with survival time. Results Seventy-two patients (25.4%) survived the period of excess mortality after intensive care unit admission. A total of 79.5% of the 283 patients required one or more surgical revisions. Besides the underlying disease and disease severity at intensive care unit admission, there was a nonlinear smoothed association between a poorer outcome and the duration of surgical therapy, and the number of surgical revisions. For the latter, hazard ratios increased sharply between 1 and 5 revisions, and remained largely constant later on. Conclusions In critically ill patients with peritonitis, a long therapy and the necessity for a high number of reoperations is related inversely to acute survival.
